Embryo Formation: Tiny Cells Start Growing
In week 3 of pregnancy, fertilization is complete and the first steps are taken for your baby to grow. The fertilized egg begins its journey to your uterus, where a miracle happens. These cells begin to multiply rapidly to form the embryo. It may not look like a baby yet, but this tiny cluster of cells will be your tiny miracle in the future.
What Can You Feel?
Most women don’t even realize that they are pregnant this week because the signs of pregnancy may not have really started yet. However, some mothers may notice signs such as tender breasts, mild crampsor tiredness. If you find out that you are pregnant this week, you will most likely have a lot to look forward to before the test results come back positive.
Your Baby’s Development
This week the embryo is still very small, microscopic and developing rapidly. The fertilized egg passes through the tubes before reaching your uterus, during which time the cells divide rapidly. Your baby’s genetic code is also determined this week; features such as eye color, hair color and height are already starting to form!
What is happening in your body?
From this week onwards, your uterus prepares to welcome the embryo. Your uterine wall starts to thicken to provide the ideal environment for the embryo to implant. Hormones play an important role in this process and you will start to feel the effects of these hormones more and more in the coming weeks. The hormone progesterone relaxes the uterine muscles and helps the embryo to attach in a healthy way.
